SUPPLEMENTAL SEAT ATTACHMENT FOR MOTOR-CYCLES AND THE, LIKE.

Specification of Letters Patent.

Patented July '7, 1914..

Application filed December 7, 1910. Serial No. 596,124.

To all whom it may concern:

Be it known that I, J osnrrr C. Fox, a citizen of the United States ofAmerica, and a resident of the city of Seattle, in the county of Kingand State of Washington, have invented certain new and usefulImprovements in Supplemental Seat Attachments for Motor-Cycles and thelike, of which the following is a specification.

My invention relates to devices of the above type adapted to be securedto the frame of a motor cycle, bicycle or the like, and has for afundamental object the provision of a novel arrangement of parts whereinthe seat is yieldingly supported.

A further object resides in the provision of an adjustable seat withmeans for securing the same as adjusted. With the above and otherobjects in view, to be referred to as my description progresses, myinvention resides in the features of construction, arrangements andcombinations of parts hereinafter described and succinctly defined in myannexed claims.

Referring to the accompanying drawings, wherein like numerals ofreference indicate like parts throughout: Figure 1 is a side elevationof a portion of a bicycle frame having my invention applied thereto.Fig. 2

is a fragmentary perspective of the inve-ntion, the seat being adjusted,as in Fig. 1, to form a back for the main seat of the machine. Fig. 3 isa fragmentary sectional view, illustrating more particularly theauxiliary seat in lowered position. Fig. 4 is a section taken on line 44of Fig. 1; Fig. 5 is a fragmentary vertical section illustrating moreparticularly the adjustable fulcrum and the means for supporting thesame on the rear axle of the machine. Fig. 6 is a detail view of one ofthe foot rest guides, and Fig. 7 is a section taken on line 77 of 4 Fig.1.

For the purpose of illustration I have shown my invention applied to abicycle or motor cycle frame, including the back fork 1, in whichismounted a wheel 5, chain stays 2, and a down tube'3 in which thepillar of the seat 4 is mounted, said wheel being mounted for rotationon an axle 6, fixed to the lower portion of fork 1 by nuts 7, all ofwhich can be of any well known or desired construction.

My invention comprises a support including a lever member 10 having anadjustable fulcrum or bearing 12, by which a variable leverage can beobtained with a resultant increase or decrease in the cushioning tensionunder which the auxiliary seat 13 is maintained. An extremely simpleconstruction results through the provision of a lever member 10 which initself is of elastic con struction, and for such reason I form thismember of a suitable length of spring sheet metal and removably secureits forward end portion, as by a clamp 11, to fork 1, such forward endportion being curved upwardly and engaged at its free end portion byclamp 11, as clearly shown in Fig. 1.

Fulcrum or bearing 12 engages member 10 at an intermediate point and isadjustable lengthwise thereof to vary the length of the projecting freerear portion, for reasons hereinbefore set forth, on which rear portionthe seat has bearing through a connection 15, to thereby impose thereonthe weight or the preponderance of weight of the rider, the latterstatement being particularly true in this the preferred embodiment of myinvention, inasmuch as mainly for the purpose of stability, I provide anadditional connection 16 between the seat and said lever memberforwardly of fulcrum 12.

Reference numeral 17 indicates spaced rigid uprights mounted for rotaryadjustment on the end portions of axle 6, and having fulcrum or bearing12 mounted on their upper end portions for free rocking movementthereon,whereby weight imposed on the rear end portion of. lever member10 tends to bow upwardly that portion of the lever member forwardly offulcrum or bearing 12, this being permitted by the upper end portions ofuprights 17 springing forward slightly, and further, through theyielding of such forward portion of member 10. Therefore, that portionof the lever member 10 between the points of connection 15 and 16 has aslight swinging movement, rocking with fulcrum or bearing 12 on uprights17, and such lever can be'rendered more or less sensitive for rockingmovement throughweight of a rider imposed thereon by varying thelengthof its projecting rear end portion, which is effected through adjustmentof fulcrum or bearing 12 lengthwise of the lever member. To prevent anyvertical shifting of lever member 10 during adjustment of fulcrum 12 inits are like path, I curve in concentric relation that portion of levermember 10 engaged thereby, as clearly shown inFig. 1.

Depending from uprights 17 are extensions 17 to which arms 19 arepivoted, as by pintles 18, for swinging eccentrically to wheel 5, thesearms carrying suitable foot rests 20 and being slidably' engaged withvertical guides 21, secured, as by clamps 22 to fork 1 and stays 2. Tocompensate for adjustment of upright members 17 arms 19' have slottedconnection therewith, pintles 1-8- being adjustably held in suitableslots of eX- tensions "17 by nuts 23 opposing centrally locatedshoulders of the pintles, as clearly shown in Fig. 7.

Inmounting foot rests 20, as just de-.

scribed, I am enabled to lift the same when;

their use is not required, and thereby over come all danger of theoperator be1ng 1njured through contact of his heels therewith.

Springs 24- serve to return foot rests 20 to and hold the same in theirelevated or positions of non-use.

In my present construction'I mount auxiliary seat 13 in a novel manner,whereby it can, as desired, be set upwardly to serve as a back for mainseat 1, in which position it is held by a rearwardly disposed brace 25.JVith this end in view, auxiliary seat 13 is hinged, at its forwardedge, to a carrier 27, with which connections 15 and 16 are portionswith nuts, as shown, the said pins directly engaged, these connectionsconveniently consisting of respective pairs of depending lugs, theformer of which are in the form of threaded stems, and having a yieldingconnection with their related clamp 28 through springs 29, whileth-elatter are.

journaled directly on the end portions of the cross bar of a clamp 30.

Clamps 28 and 30 which can be of any desired constructlon, are shown asCOl'lSlSi]:

ing of cross bars engaged on the upper face of lever member 10' andhaving dependlng pins, provided on their threaded lower end beingadapted to be seatedin any of the notches of respective series, the rearseries of which are formed in the longitudinal edge portions of the rearend portion of member 10 which is substantially horizontal, v

whereby. a lengthwise adjustment of carrier 27 can be effected withoutdisturbing the set thereof in a vertical direction.

Brace25 has its lower end releasably connected with the horizontal crossbar of clamp 30' held in depending bracket arms of carrier 27 and hasits upper end slotted for reception of a threaded stem, the latterreceiving a clamping nut and forming in conjunction therewith a clamp 32for holding the seat and brace agalnst relative movement. As nowconsidered, the lower end portion of brace 25 is bifurcated and thesefurcations project through slots 27 in car rier 27 and receive supportin a rearward direction from the back walls thereof, and have their proecting portlons bent to form hooks 33 which are releasably engaged withcross bar of clamp 30, these hooks: being so shaped that their releasecan be effected after brace 25 is swung forwardly slightly past normalposition, said brace being then forced downwardly, subsequently to itsrelease from clamp 32, after clearingwhich, it can,,with the carrierstill held in its forwardly disposed position, be elevated above saidcross bar of clamp 30, then adjusted to the position shown in Fig. 3,whereby its bifurcated end portion will lie over said clamp cross bar,during swinging of the seat to itshorizontal position, in which theprojecting parts of clamp 32 will be received in a slot 27 of thecarrier. I A convenient mode of hinging seat 13 to carrier 27, ashereinbefore described, con sists i-n removably securing the seat to asuitable frame 36, by the flexible connections37, which frame andcarrier 27 are of plate sections hinged at their forward edge portions,as at 26, which engagement per: mits of carrier 27 being employed as aparcel support, when the seat is swung upwardly. Y

Referencenumeral 38 indicates the auxiliary handle bars convenientlyheldon lever member 10, forwardly of seat 13, asby a clamp 39.

Fulcrum or bearing 12, as now considered,

comprises a cross bar. provided with angle lugs 12 embracing the sideedge portionsof lever member 10, and carrying lock pins .12 adaptedforinsertion in suitable notches i0, of said lever member as clearly shown.
